Characterization of highly polymorphic nuclear microsatellite loci from the ascidian Ciona intestinalis
Authors:N. ANDREAKIS  L. CAPUTI  P. SORDINO
Abstract:
Eight nuclear polymorphic microsatellite markers were characterized from the ascidian Ciona intestinalis whole genome sequence. The behaviour of these loci was investigated against two geographically distinct populations: one from Plymouth, UK the other from the Fusaro Lagoon, Italy, both belonging to the type A Ciona cryptic species. The markers exhibited six to 29 alleles and average observed heterozygosity ranging from 0.06 to 0.73. These new microsatellite loci demonstrated to be valuable tools for both population genetic analysis at different scales and genetic identification of mutant phenotypes frequently encountered in Mediterranean populations of C. intestinalis.
Keywords:Ciona intestinalis  cryptic species  Mediterranean populations  microsatellites  mutant phenotypes
